I've googled around enough to see that this is a common issue, but
haven't found a definitive answer on how to access a value from the
params hash in a before_filter. I'm currently trying this:
before_filter :only => [:create, :update, :destroy] do |controller|
controller.bounce_if_unauthorized params[:token]
end
with the following in application_controller.rb:
protected
def bounce_if_unauthorized token
puts token
redirect_to root_path,
:alert => 'You are not authorized.' unless token == 'abcde'
end
but the equality is never true. Meanwhile, the verify method mentioned
at http://guides.rubyonrails.org/action_controller_overview.html#filters
is no longer listed in the API, so that's probably not the way to go
either.
How can I create a before_filter based on an element of the params
hash?
